Specification of Letters Patent.

Patented Sept. 1, 1908.

Application led February 8, 1908. Serial No.' 415,001.

A further object of the invention is toprovide the vertical rails 'of the-sliding saslies with spaced flanges for engagement with the adjacei'it window stops, the latter being provided with lateral guide lips which bear against the saslies thereby to reduce frictiony to a minimum and render the window practically weather proof.

A further object is to form the meeting rails of one. of the saslics with a longitudinal flange which bears against the inclined face of the meeting rail of the adjacent sash when said sashcs/are in closed position, thereby to pri-)duce an intermediate air space or chamber.

A further object is to so arrange the sashes with respect to the window frame as to form vertical air cushions on opposite sides of the window and further to provide iniproved means for securing the stops in position on said frame.

A still further object of the invcntion'is generally to improve this class of devices so as to increase their utility, durability and cllicieiicy.

l `urther objects and advantages will appear in the following description, it being understood that various changes in forni, proportions and minor details of. construetion may be resorted to within the scope of the appended claims.

'llie improved Window'forining the sub-A ject matter of. the -present invention comprises a hollow sup iorting frame or casing 5 preferably formed off sheet metal and in which is mounted vfor sliding movement the Extend-ing transversely across the side members of the. fraiiieor cas .ingv is an intermediate partition 8 forming vpockets orl com'partnients- E) vfor the reception .of the sliding weights (ir-counter balances 10. 'llic side men'ibers are reinforced andk strengthened by the provision. of metallic braces 11, which lattenextend the entire width of the franie and are riveted or otherwise rigidly secured to the metal forming the inner section of the wiiidowfranie,as indicated at 12. 'lhe'inetalforming' the outer section of the frame is lapped over the adjacent ends of the, inner section at 13, said outer section being )rovided with an intermediate longitudinally disposeil rib 14 for the reception of the partition 8 thereby-to prevent accidental displacenientof the saine.

The intermediate 'portion of each plate 11 is bent inwardly to )reduce a ylongitudinal reinforcing rib 15 deiining a seating groove 16 for the reception ofthe 'central Window stop 17. The window step 17 is preferably constructed from a single piece of sheet metal bent to forni oppositely disposed contact lips 18 tern'iinating in a reduced shank 19, which latter is seated within the groove 16 and is retained in position on the window frame by screws or similar fastening devices 20. 'lhe screws 20 are disposed at spaced intervals on the window stop and are thread? ed in suitable openings .21 formedin the reinforcingbeiul 15 thereby to 'firmly clamp the stop 17 in engagement with the window fraine. ',llie inside window'stop 22 is similar in construction to the' central stop 17 and is also retained in position on the window frame by one or more screws 23.

The reinforcing plate 11 is oit; set at the inside of thewindow frame and the metal tlieiniier section of the vwindow comprising frame extended outwardly at the ofi set portion 34 to form reinforcing beads 25 and 26, which latter are spaced apart to permit the introduction of the shank of the inside stop 22.

A longitudinal rib or flange 27 is extended laterally from the reinforcing plate il and is provided with a terminal head or lip 23 which corresponds to the lips i8 of the central stop 17, said flange constituting the outside stop of the window and being so ai'- ranged as to bear against the adjacent side rail of the upper sash 6.

The sliding sashes 6 and 7 are also preferably hollow and constructed of slicetmetal, the longitudinal edges 2f) of the side rails of the sashes being extended laterally to form inclined uide flanges 3() which over-lap the ed es o the metal constitutingr the bod of the sas and are riveted, welded or ot ierwise ri idly secured thereto. The longitudinal v e ges of the sliding sashes are spaced from the inner 'faces of the `window frame or casing to form an intermediate air chamber or cushion 31, there being loops or eyes 32 secured to the longitudinal ed fes 29 of the sashes 'for en.

gagement with a c lain or other flexible connection, indicated at 32. "llie chains 32 pass over suitable pulleys 33 and are extended downwardly within the compartments l) lfor attachment to the weights l() thereby to ei)unter-balance the sashes.

Attention is here called to the fact that the flanges 3() bear against the shanks of the ad- .picent window sto )s while. the lips I3 and 2S' iear against the a( jacent walls ol' the sliding sashes l thus reducing friction between the parts to aV minimum, while at the same time permitting a close fitting sash which is practically weather proof'.

'lhe lintel 34 of the frame or casing is also reinforced and strengthened by a metallic plate 35, there being spaced depending ribs 36 formed on the bottom of the pla'te 35 and between which the u )per sash 6' is seated when said sash is in closed position, as best shown in Fi f. 6 of the drawings. y l',

'lhe top rail of the upper sash 6 is provided with a sheet metal cover or cap piece 37 having its opposite longitudinal edges bent to form depending flanges 38 which engage seating grooves formed in the metal comprising the body portion of said sash, the walls of the seating grooves being extended laterally beneath the plate or cap 37 to form supporting flanges 39.

As a means for locking the plate or cap piece 37 in position on the upper sash there is provided a screw 40 carryin a turn button 4l whichbears against'the anges 39 when the screw is rotated thereby to lock the parts in assembled position.

.Extending vertically from and preferably formed integral with the reinforcing plate of the lintel 34 are spaced brackets 42 in which is mounted a shaft 43 carrying the pulleys 33, the latter being mounted for independent rotation on the shaft 43, as shown.

The base or sill 44 of the window frame or easing is preferably filled with cement, concrete or other plastic material and is prod vided with a plurality of stepped shoulders 45, one of which is ada )ted to receive the lower transverse rail of ilhe sash 7 when the latter is in closed position.

",lhe metal forming the lower rail of the sash 7 is extended downwardly beyond the base 46 of said sash to produce a depending lip 47 which engages the inclined shoulder 48 of the sill thereby to assist in preventing the entrance of air orA moisture between the lower sash and sill. i

The lower sash is also preferably provided with asuitable handle or `finger piece 4i) by means'of which the lower sash maybe moved to raised or lowered position.

The metal forming the base of the meeting rail of the up )er saslr is extended laterally to produce a liorizontally dis )osed flange 5() which bears against the inclined face 5l of the meeting rail of the lower sash 7 when said sashes are in closed position thereby to form an intermediate air chamber or cushion 52y at the juncture of said sashes so as to render the same weather proof.

'l`he meeting rail of the lower sash is reinforced by the provision of a plate preferably in the form of an angle iron 53, which latter extends the entire width of the sash and forms a sup )ort for one element of a suitable fock-ing device 54, the other element 55 of the locking device being supported by a reinforcing' plate 56 secured to the meeting rail of the up )er sash 6.

. he inuntin 57 is provided with the usual seating grooves for the reception of glass or other transparent material 53.

While it is preferred to construct the window with sliding sashes each having a weight or counterbalance, it is obvious that the weights may be dispensed with and the sashes connected, by a cord, chain or other flexible medium so as to balance each other.

'lhe window frames may be made in different sizes and shapes and the metal stamped, embossed or otherwise pressed or formed with ornamental designs so as to give the window a neat attractive appearance.

From the foregoing description it will be seen that there is provided a window which is strong and durable in construction and thoroughly efficient in operation and which is )ractically Weather and fire proof.
